EDOCROS (EUFAR
Transnational Access project)
Early detection of crop
water and nutritional stress by remotely sensed
indicators
|
|
The objective of the EUFAR
Transnational Access project "EDOCROS" is to test
hyperspectral indices (PRI and Fs) at canopy and
landscape scale for the early detection of water and
nitrogen (N) deficit, in order to provide irrigation and
fertilization prescribing maps. Optical indices
performances will be compared with thermal indicator
(brightness temperature Ts and derived crop stress
indices) and surface energy balance methods in order to
verify their reliability in water stress detection.
Dual-source energy balance algorithms will be applied by
using high-resolution radiometric temperatures for
estimating actual evaporation fluxes at the instant of
acquisition.
Field radiometric measurements and airborne image
acquisition will allow to test different techniques and
to scale procedure from field canopy level to landscape
level. Vegetation biophysical parameters and
eco-physiological parameters measured in field during
the airborne survey, will provide a description of crop
status.

Verso l’individuazione
di indicatori precoci dello stress idrico e carenza di
nutrienti in agricoltura: sviluppo di metodi innovativi
di telerilevamento iperspettrale da aereo
|
|
The project aims to develop
a vegetation stress monitoring system at landscape
scale. This system is based on early detection
indicators mapped from remotely sensed data acquired by
airborne sensors. Different remote sensing techniques
were tested on an experimental field where 48 corn and
sorghum parcels were grown with different water and
nitrogen treatments. Different narrowband vegetation
indices related to biochemical and physiological
variables (e.g. Photochemical Reflectance Index – PRI)
were calculated, and relative values of sun-induced
chlorophyll fluorescence at 760 nm (F760) were retrieved
by remotely sensed data. Furthermore, vegetation
temperature was estimated by an image acquired by a
thermal sensor in order to test its suitability for
stress monitoring. Maps of water and nitrogen stress
were produced on the experimental site. The method
proposed can be applied in agro systems in order to
produce water and nitrogen prescribing maps, toward a
more sustainable use of water and nitrogen in
agriculture. |

COST ACTION
ES0903
Spectral
sampling tools for vegetation Biophysical Parameters and
Flux measurements in Europe
|
| The COST
action ES0903 “Spectral sampling tools for vegetation
Biophysical Parameters and Flux measurements in Europe”
was funded in 2009 by the European Science Foundation.
The main objective of the Action is to define common and
standardized protocols and to develop new instruments
for optical measurements at flux tower sites. In this
context, the Action sets out to join together scientists
and industries to improve the methodologies for proximal
optical sampling.

PhenoALP
Alpine Phenology
|
| The PhenoAlp transborder project, led by the Aosta valley region (I) aims to set up an integrated methodology for the analysis of
the effects of climate change on the phenology of vegetation and animals in the Alps. Besides the scientific research dimension of the project, PhenoAlp partners will engage in concrete monitoring, realized in a participatory spirit in order to raise awareness about alpine environmental challenges towards the public at large but also in schools. |

HSI
Robotic HyperSpectral Irradiometer
|
This project consists in the development of a robotic irradiometer designed for continuous and long term optical sampling of vegetated surfaces in order to monitoring daily and seasonal trend of steady state fluorescence at Oxygen A-Band (Fs@760nm), Photochemical Reflectance Index (PRI) and traditional Vegetation Indexes (VIs). This system is expected to provide an estimation of parameters and processes useful to explain water and carbon fluxes components measured at the eddy station. Installation of the HIS was carried out in summer 2008 at the IES-JRC experimental site of Castellaro (Italy).
